This really works. Hands down this is the best battery charger I have ever owned. Well worth the price!

The product works well. The description does not explain the mechanism for fixing batteries.

Very good product I love this machine charges very well and quick

I have been using this charger for years now to recharge 18650 batteries that I salvage from old battery packs. It has never failed me.

LiitoKala makes some of the best chargers. Having12 slots is why I got this unit. For the money though I think it should gave some additional features such as testing and perhaps repair. An on/off switch would be nice and why are the 9v charger lights always on although not being used. Annoying.

excellent

I also own a smaller version of the same charger which I was mostly happy with so I decided to get the bigger. As I used them more and more, well I'm not quite as happy with them.For the most part, they're OK, you drop a battery in, it charges and you pull it out, but lately, I've run into a few 18650s (more than one brand, more than one capacity) that just do not seem to charge right. I charge them, it says they're done and I drop them back in the light that I had them in and the light is dim. I check the voltage and the voltage is low. I haven't quite figured out what the problem is and I haven't given up on the charger (both seemed to work well initially and they seem to work fine on all the other batteries) so so far that's maybe a star or a little less off.The next bit, again, not maybe a whole star- the terminals are flat, there is no bump to firmly engage the battery, so batteries with flat ends don't tend to make contact well. OK, some oddball batteries need some fidgeting, but I have had it where I drop a battery in, I think it's OK and I come back later and it's not charging, not connected.Finally, at this price, I feel like this should have more testing and other features. Now admittedly I haven't found anything cheaper that does more without having to "make" something myself, but it is possible, and with all the battery tech out there now it really is kind of necessary, again, not really a full star thing, so I ended up at 3 stars.

A+
